Although they have previously issued coins, most presumably NCLT crowns, Tristan da Cunha has issued a set of base metal circulation issues (although I wonder how much they will really circulate on the island, and how much is just for profit).

Image hi-jacked from an eBay auction:

I forgot to put the obverse image.

Oh bugger, wish I had seen this the other week, would have been a bit of an interesting set to have had

EDIT: Oooh just got some, will post pics when get them.

Do you think these coins is legal tender?

sure. but the question is "do the 270 people on tristan da cunha actually use these?" i bet not.

Yea, I think they will not, same as Pitcairn, Nightingale, Cocos and etc..

Those are beautiful coins
